LIQUID-AGITATOR.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed October 27,1904. Serial No, 230,271.

To all whom it may concern;

Be it known that I, ADAM G001), a citizen of the United States, and aresident of Olaflin, in the county of Barton and State of Kansas, haveinvented a new and Improved Liquid- Agitator,of which the following is afull, clear, and exact description.

My invention has for its object the improvement of devices for agitatingliquids for various purposes such as mixingliquids,churn ing butter,85c. ltmay also be used for aerating milk and other liquids.

My invention further consists in the construction and combination ofparts, as will be more fully described in the detailed descriptionappended hereto and definitely set forth in the claim.

Reference is to be had to the accompanying drawing, forming a part ofthis specification, in which the figure is a side elevation of myinvention complete with part in section.

Upon a base 1 is mounted a cylindricalaircompressor 2, with openings inthe cylinderheads 3 1 and connections 5 6 made thereto. Theseconnections communicate with intakevalves 7 8, which act only in onedirection. They also communicate with similar valves 9 10, which act inthe opposite direction and allow air to pass only when under compressionsufficient to open said valves. The valves 7, 8, 9, and 10 are ordinarycheck-valves and are well known in the art to which they belong. Thevalves7and 8 are in immediate communication with a common supply -pipe11. An oil-cup 2 is provided for lubricating the aircompressor.

In the preferable form of my compressor I use ahand-lever 12, connectedby a pivot-pin 13 toa link 14, which is pivotally mounted on thecylinder 2. The lower end of the lever 12 is connected by a pivot-pinwith a piston-rod 16. By this means a powerful stroke can be given thepiston in the compressor. By means of holes 13 in the lever 12 and holes13 in the links 14 the pivot-pin 13 may be so adjusted as to vary theleverage of the hand-lever 12.

Supported above the base 1 is a receptacle 17, which is adapted tocontain the liquid to be acted upon. This receptacle may, however, bemounted upon a separate support if so desired. It consists, preferably,of sheet metal and has a cone-shaped bottom 18 and is provided with acover 19 for excluding dust, dirt, 8:0. The side of the receptacle isprovided with an outlet 20, having a valve 21 therein for closing thesame. At a higher point in the side of the receptacle is a spigot 22 ofany ordinary construction. To indicate the heightof the liquid in thereceptacle when the same is made of sheet metal or other opaquematerial, a gage-glass 23, mounted in settings 24, is connected at thelower point of the receptacle and also at a point above the same, sothat all heights of liquid are indicated. If desired, this receptaclemay be made entirely of glass, so that the action of the air upon theliquidis readily seen.

At the apex of the cone-shaped bottom 18 are connected two pipes 25 25*,provided, re-

spectively, with check-valves 26 26. Above these check-valves arelocated Ts 27 27 To these Ts are attached outlets 28 28 29 29. Eachcheck-valve 26 26 is so arranged that it will allow air to pass upwardinto the receptacle 17, but will prevent a downward flow of the liquidwhen the pressure of the air is removed. Each pipe 25 25 is directlyconnected with the air-compressor by means of connections to the pipe11. Hand-valves 3 0 30 31 31 are used for removing the liquid from thereceptacle 17.

Between the air-compressor and the pipe 25 on the pipe 11 is located athermometer 32, a pressure-gage 33, and relief-valve 3 1. Thethermometer is intended to record the temperature of the air undercompression, the gage indicates the pressure of the same, and therelief-valve can be adjusted for the amount of pressure required for theproper action of the air upon the liquid.

By so locating the pipes as to introduce an into the liquid at thebottom thereof one or more streams of air are forced directly into theliquid, and there is no loss of pressure due to the air striking thesides or bottom. The advantage of having the cone-shaped bottom is thatthe air expands more readily through all parts of the liquid, and thusproduces the is used, and by means of it the pressure required for theparticular liquid to be acted upon can be nicely adjusted,

\Vhile the above is a description of one of means for establishingcommunication between said connections and the ends of said cylinder, areceptacle for a liquid, and a pipe connected with both discharge 7outlets and with said receptacle for said liquid.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ADAM GOOD.
